Rupert Murdoch
Net worth: $ 7.6 billion
Company: Myspace
Murdoch is rumored to be looking to sell money-losing Myspace, which he bought in 2005 for $ 580 million. His traditional media fares better; Fox News made $ 700 million in operating profit in 2010. The Super Bowl on Fox was the most-watched TV broadcast ever. His Wall Street Journal keeps expanding while others shrink. Thanks to a close relationship with Apple, his News Corp. added digital subscriptions on the iPad with the $ 30 million launch of The Daily in February.
